Monitor Water Quality
Use a water quality sensor, turbidity sensor, and weather/anemometer sensor to monitor the pH, dissolved oxygen content, conductivity, and turbidity of a natural body of water, determining how water quality changes in response to changes in environmental factors.
Students monitor the quality of a natural body of water in several locations to determine how water quality changes in response to changes in environmental factors. They also:
- Make measurements that can be reliably compared to measurements made with different equipment or at other times, or both.
Students gain experience conducting the following procedures:
- Calibrating electronic sensors.
- Measuring parameters of water quality and interpreting the results.
- Comparing the results of measuring water quality factors in situ with measurements of water samples removed from the source.
Sensors / Equipment Used:
MultiMeasure sensor that incorporates pH, conductivity, temperature, and the optical dissolved oxygen probe.
Measures the turbidity level (cloudiness) of water in nephelometric turbidity units (NTU). For use with PASPORT Interfaces.
The Weather Anemometer Sensor measures wind speed and wind chill in addition to temperature, barometric pressure, relative and absolute humidity, and dew point.
Collects GPS data simultaneously with other sensor measurements, automatically syncing the data to your latitude, longitude, altitude, and velocity. For use with PASPORT Interfaces.
Sensor User Guides with calibration instructions and tables - Several
Chemical test kit (optional)
Duct tape, roll
Long-handled sampling device
Wading boots (optional) - 1 pair
Wash bottle containing distilled or deionized water
